Answer the following questions about the science and math behind boiling eggs!
Science of Boiling Eggs
1. What happens to the proteins in egg whites when you boil them?
2. Why does the egg yolk harden as it cooks?
Math of Boiling Eggs
3. If it takes 10 minutes to boil water and 5 additional minutes to cook the eggs, how much time does it take in total to have ready-to-eat eggs? (Show your math)
4. Eggs can be boiled for different lengths of time to achieve desired doneness. If you prefer a runny yolk and cook the eggs for 6 minutes, but your friend prefers a fully cooked yolk and cooks them for 12 minutes, what is the difference in cooking time? __________ (minutes)
Calculating Cooking Time
5. Eggs typically take about 3 minutes per millimeter of shell thickness to cook. If an egg has a shell thickness of 0.5 millimeters, how long would it take to cook? (Show your math)
6. Create a small table below showing different boiling times and the corresponding doneness of the egg yolk (liquid, slightly firm, or fully solid).
Think Deeply
7. If you left the eggs in the boiling water for twice the recommended time, what do you think would happen to the texture and taste of the eggs? Why?
